Abstract:
   Bit Index Explicit Replication (BIER) is an architecture that
   provides multicast forwarding through a "BIER domain" without
   requiring intermediate routers to maintain multicast related per-flow
   state.  Neither does BIER require an explicit tree-building protocol
   for its operation.  A multicast data packet enters a BIER domain at a
   "Bit-Forwarding Ingress Router" (BFIR), and leaves the BIER domain at
   one or more "Bit-Forwarding Egress Routers" (BFERs).  The BFIR router
   adds a BIER header to the packet.  Such header contains a bit-string
   in which each bit represents exactly one BFER to forward the packet
   to.  The set of BFERs to which the multicast packet needs to be
   forwarded is expressed by the according set of bits set in BIER
   packet header.

   This document describes the OSPFv3 [RFC8362] protocol extensions
   required for BIER with MPLS encapsulation [RFC8296].  Support for
   other encapsulation types is outside the scope of this document.  The
   use of multiple encapsulation types is outside the scope of this
   document.
